Just an update for future searchers: So I placed various bushings in my friend's hardness tester. Here's how it turned out:
From left to right:
70A - The sonex bushing
75A - the blue bushing from Amazon
85A - Ninjaflex printed polyurethane
95A - Too hard printed polyurethane
My personal plan is to fly with the sonex bushings (with washers) and see how it goes. If encounter significant droop I'll (someday) try the 85A bushings.
